The sticker on our electric step noted a lubrication recommendation of every 30 days. Which I do not believe the previous owner followed, as the first time I lubed the step it made a major difference in the operation. I still do this on about a once-a-month basis, depending on the use of the RV. Apply a little synthetic grease with a flux brush. With a shop rag to first clean the contact areas. Easy enough to be worth the effort.
